DNG or Digital Negatives are imaging specifications that provide long-term storage for digital images that are in various proprietary formats. DNG’s were devised by Adobe to tackle the problem of the growing number of undocumented raw file formats that are produced each time a new digital camera is introduced into the market.
Owing to the compact format and open standard of DNG files, converting raw files into DNG format has numerous advantages. Open standard conveys that the file format specification is freely available to third-party developers. Therefore, programs other than Adobe’s Photoshop and Lightroom can read from and write DNG files. Moreover, DNG files tend to be smaller in size as compared to the original raw files.
Additionally, while using applications such as Lightroom, one can create photo merged panoramas or HDR images with files saved in DNG format. This helps retain the raw characteristics from the source images. However, converting raw files to DNG also has disadvantages.
